Có thể chỉ là cọng cáp chưa thật chắc chắn, thử lại coi sao!

Nếu được gỡ main ra ốp cho thật chắc chắn

cáp chưa chuẩn rồi bạn ơi hoặc bạn làm lại cpu đi nha...

Thank tất cả các bro, mình xem kĩ lại tất cả rồi, cpu bị đứt mạch từa lưa hết, mình đã trả máy cho khách luôn rồi. nhưng mới thì mình cũng vừa nhận 1 con 7260 bị y như vậy, flash nó cũng báo lỗi y như trên.
